L’objectif de cet article est d’analyser les variations spatiales la létalité hospitalière due à Covid-19 en France métropolitaine pendant première vague l’épidémie. Les résultats montrent une corrélation positive significative entre niveau morbidité et taux létalité. Cependant, l’ampleur cette augmentation ne peut expliquer des reportés par pays qui peuvent provenir que systèmes déclaration ca...

Determination of negative skin friction force and The neutral plan is one the challenges which face geotechnical engineers. Unfortunately, decreases bearing capacity pile because extra compressive on pile. In this research, a 3D FE models were used to investigate behavior single group in soft soil for surcharge load as embankment fill. And what are differences that will happen group. For fill l...

The construction of offshore wind power pile foundations on artificial islands is a challenging task due to soil consolidation and additional loads that result in negative skin friction (NSF). In this study, comprehensive pile–soil interaction model established investigate the development NSF under action self-weight fill surcharge load. one-dimensional theory an ideal elastoplastic load transf...

The performance of passive battered piles resisting the embankment-induced lateral soil movements may differ from that active pile and axially loaded existing vertical adjacent to embankment constructions. This study was part a preliminary feasibility investigation for reinforcement plan an actual project, aiming experimentally investigate under movement. To this end, sequence reduced-scale mod...

Concerns about climate change have led to calls for reforming or eliminating the extensive US federal fossil fuel leasing program. One proposed reform is adding a surcharge existing royalty rate. We consider determining this by maximizing social welfare, including damages from combusting fuels and value of raising revenue when marginal public funds exceeds one. estimate that resulting would lea...

12-molybdophosphoric acid (pmo12) was encaged into hmor zeolite by “ship in a bottle”method in aqueous phase which is strongly retained and not easily leached from the host channels.the solid was characterized by xrd prior to using it for the electrode preparation. this compoundwas incorporated with a carbon paste electrode for cyclic voltammetric measurements. pmo12immobilized on the support u...
